Cover illustration: The arrangement of two adjacent strands in the monoclinic unit cell of catena-poly[[(tetra­hydro­furan-O)potassium]--(5:5)-2,3,4,5-tetra­methyl-1-n-pentyl­cyclo­penta­dien­yl], viewed along the [010] direction. For the sake of clarity, H atoms and the minor disordered component of the disordered THF ligand are not shown. See Seidel, Ganesamoorthy, Loerke, Winter, Gemel & Fischer [Acta Cryst.
